Macaroni and Cheese with Mornay Sauce

Ingredients

  • 1/2 pound dried elbow macaroni
  • Coarse salt and freshly ground pepper
  • 3 tablespoons unsalted butter
  • 1/4 cup all-purpose flour
  • 3 cups whole milk
  • 1/2 cup finely grated Italian fontina cheese
  • 2/3 cup finely grated Gruyere cheese
  • 1 2/3 cups finely grated extra-sharp white Cheddar cheese
  • 1/2 cup finely grated Parmigiano-Reggiano cheese
  • 1/8 teaspoon cayenne pepper
  • 1/8 teaspoon freshly ground nutmeg
  • Pinch of white pepper

Directions

  1. Bring a large pot of water to a boil, then add pasta; salt generously and cook pasta to manufacturer’s instructions. Transfer to a colander, rinse under cold running water, and drain well.
  2. Melt butter in a 4-quart pot over medium heat. Whisk in flour and cook, stirring with a wooden spoon, until bubbling but not browning, about 45 seconds. Add milk and whisk to combine. Bring to a simmer, stirring with a wooden spoon (scrape across the bottom and around edge of pot to prevent scorching), until thickened and smooth. Reduce heat to a simmer and cook for 20 minutes.
  3. Add fontina, Gruyere, Cheddar, and Parmigiano-Reggiano cheeses, stirring until completely melted and sauce is smooth. Season with salt and black pepper, add cayenne and nutmeg, and stir to combine.
  • Add pasta to sauce along with white pepper and salt; stir to thoroughly combine. Serve immediately.
